Keys to the doors of the kingdom is the word, the seed in the beginning (Mark 4:13), (Luke. 8:10), which is the parables. In them is the Mystery of the ‘Kingdom of God:’ It starts with the Sabbath (7th day of rest), of which Yahsua, (Jesus) is Lord of.
(Luke 6:10) 10 And He said, “To you it has been given to know the mysteries of the kingdom of God, but to the rest it is given in parables, that ‘Seeing they may not see, and hearing they may not understand.’
(Mark 3:27-28) 27 No one can enter a strong man’s (the Devil) house and plunder his goods, unless he first binds the strong man. And then he will plunder his house. 28 “Assuredly, I say to you, all sins will be forgiven the sons of men, and whatever blasphemies they may utter;”
(Matthew 16:19) 19 And I will give you the keys of the kingdom of heaven, and whatever you bind on earth will be bound in heaven, and whatever you loose on earth will be loosed in heaven.”
(Mark 3:4-6) 4 “Then He (Jesus) said to them, “Is it lawful on the Sabbath to do good or to do evil, to save life or to kill?” But they kept silent. 5 And when He had looked around at them with anger, being grieved by the hardness of their hearts, He said to the man, “Stretch out your hand.” And he stretched it out, and his hand was restored as whole as the other. 6 Then the Pharisees went out and immediately plotted with the Herodians against Him, how they might destroy Him.”
(Mark 3:14-15) “Then He (Jesus) appointed twelve, that they might be with Him and that He might send them out to preach, 15 and to have power to heal sicknesses and to cast out demons:”
(John 14:12) 12 “Most assuredly, I say to you, he who believes in Me, the works that I do he will do also; and greater works than these he will do, because I go to My Father.”
(Mark 3:22) 22 “And the scribes who came down from Jerusalem said, “He (Jesus) has Beelzebub,” and, “By the ruler of the demons He casts out demons.”
(Mark 3:26-30) 26 “And if Satan has risen up against himself, and is divided, he cannot stand, but has an end. 27 No one can enter a strong man’s house and plunder his goods, unless he first binds the strong man. And then he will plunder his house. 28 “Assuredly, I say to you, all sins will be forgiven the sons of men, and whatever blasphemies they may utter; 29 but he who blasphemes against the Holy Spirit never has forgiveness, but is subject to eternal condemnation”– 30 because they said, “He has an unclean spirit.”
